About us

Our service covers the four key areas of network management, asset management, area operations and business management.

Network management

Our Network Management function is responsible for day-to-day monitoring and the availability of the road network. It includes operation of the South Wales Traffic Management Centre control room, the Traffic Officer Service and coordination of works on the highway.

Asset management

The agency is responsible for maintaining the condition and value of the Welsh Government’s trunk road assets. Assets include:

Capital schemes are designed to improve a part of the trunk road network and enhance its value over an extended period of time (as opposed to maintenance of the existing asset). They include the cost of procuring, constructing and installing the new element of the network, whether for replacement of worn or obsolete assets or as an addition to the existing network.

Area operations

Our Area Operations function inspects and ensures the condition of structural, electrical and technology assets. The Area Teams are responsible for the implementation and annual delivery of routine and cyclic maintenance programmes through Service Level Agreements with the Agency's Service Providers. The other primary requirement of the Area teams is to deliver its delegated functions on behalf of the Welsh Government to undertake the requirements of the Highways Act 1980 & New Roads and Street Works Act in relation to coordination, agreement and enforcement of highway related issues.

SWTRA is managed from its head office in Llandarcy, off M4 Junction 43. It is supported by regional operational offices at St Clears and Wilcrick. Network control is operated from the South Wales Traffic Management Centre, Cardiff.

SWTRA delivers functions delegated by the Welsh Ministers and which are prescribed under the Highways Act 1980 and New Roads and Street Works Act 1991 in relation to works co-ordination, licencing and enforcement in relation to highway matters
